The next XVG? Microcap 100x potential actually supported by fundamentals!
What’s up team? I have a hot one for you. XVG returned 12 million percent in 2017 and this one reminds me a lot of it. Here’s why: Mimblewimble is like Blu-Ray compared to CD-ROM in terms of its ability to compress data on a blockchain. The current BTC chain is 277gb and its capacity is limited because every time you spend a coin, each node needs to validate its history back to when it was mined (this is how double spending is prevented). Mimblewimble is different - all transactions in a block are aggregated and netted out in one giant CoinJoin, and only the current spending needs to be verified. This means that dramatically more transactions can fit into a smaller space, increasing throughput and lowering fees while still retaining the full proof of work game theory of Bitcoin. These blockchains are small enough to run a full node on a cheap smartphone, which enhances the decentralization and censorship resistance of the network. The biggest benefit, though, is that all transactions are private - the blockchain doesn’t reveal amounts or addresses except to the actual wallet owner. Unlike earlier decoy-based approaches that bloat the chain and can still be data mined (XMR), Mimblewimble leaves no trace in the blockchain, instead storing only the present state of coin ownership. The first two Mimblewimble coins, Grin and Beam, launched to great fanfare in 2019, quickly reaching over $100m in market cap (since settled down to $22m and $26m respectively). They are good projects but grin has infinite supply and huge never-decreasing emission, and Beam is a corporate moneygrab whose founding investors are counting on you buying for their ROI. ZEC is valued at $568m today, despite the facts that only 1% of transactions are actually shielded, it has a trusted setup, and generating a confidential transaction takes ~60 seconds on a powerful PC. XMR is a great project but it’s valued at $1.2b (so no 100x) and it uses CryptoNote, which is 2014 tech that relies on a decoy-based approach that could be vulnerable to more powerful computers in the future. Mimblewimble is just a better way to approach privacy because there is simply no data recorded in the blockchain for companies to surveil. Privacy is not just for darknet markets, porn, money launderers and terrorists. In many countries it’s dangerous to be wealthy, and there are all kinds of problems with having your spending data be out there publicly and permanently for all to see. Namely, companies like Amazon are patenting approaches to identify people with their crypto addresses, “for law enforcement” but also so that, just like credit cards, your spending data can be used to target ads. (A) Coinbase is selling user data to the DEA, IRS, FBI, Secret Service, and who knows who else? (B) What about insurance companies raising your premiums or canceling your policy because they see you buying (legal) cannabis? If your business operates using transparent cryptocurrency, competitors can data mine your customer and supply chain data, and employees can see how much everyone else gets paid. I could go on, but the idea of “I have nothing to hide, so what do I care about privacy?” will increasingly ring hollow as people realize that this money printing will have to be paid by massive tax increases AND that those taxes will be directly debited from their “Central Bank Digital Currency” wallets. 100% privacy for all transactions also eliminates one HUGE problem that people aren’t aware of yet, but they will be: fungibility. Fungibility means that each coin is indistinguishable from any other, just like paper cash. Why is this important? Because of the ever-expanding reach of AML/KYC/KYT (Anti-Money Laundering / Know Your Customer / Know Your Transaction) as regulators cramp down on crypto and banks take over, increasingly coins become “tainted” in various ways. For example, if you withdraw coins to a mixing service like Wasabi or Samourai, you may find your account blocked. (C) The next obvious step is that if you receive coins that these chainalysis services don’t like for whatever reason, you will be completely innocent yet forced to prove that you didn’t know that the coins you bought were up to no good in a past life. 3 days ago, $100k of USDC was frozen. (D) Even smaller coins like LTC now have this problem, because “Chinese Drug Kingpins” used them. (E) I believe that censorable money that can be blocked/frozen isn’t really “your money”. Epic Cash is a 100% volunteer community project (like XVG and XMR) that had a fair launch in September last year with no ICO and no premine. There are very few projects like this, and it’s a key ingredient in Verge’s success (still at $110m market cap today despite being down 97% since the bubble peak) and why it’s still around. It has a small but super passionate community of “Freemen” who are united by a belief in the sound money economics of Bitcoin Standard emission (21m supply limit and ever-decreasing inflation) and the importance of privacy. I am super bullish on this coin for the following reasons:
Only $400k market cap
Supply started at zero, so there are no VC’s and team to dump on you into the pumps - all coins are mined into existence, just like Bitcoin.
It just had its first halving, reducing emission from 16 to 8 per block. Between now and 2028 there are FOUR (!) more halvings, from 4 to 2 to 1 and then finally 0.15 (I guess that would be an 85%-ing :p) and at this point the supply is the same as BTC and stays in sync forever until the last coin is mined in 2140. This simple supply curve is already accepted by the market as a winner, so why mess with success? (I)
Meets Andreas Antonopolous’ 5 pillars of open blockchains test: Public, Open, Borderless, Neutral, and Censorship Resistant. (How many coins can say this?)
Unlike Bitcoin, Epic created a multi-algorithm approach that enables people to mine on ordinary computers - 60% for CPU on RandomX, 38% for GPU on ProgPow, and 2% for ASIC’s on Cuckoo31+. The algorithms don’t compete with one another. This is essential for leveling the playing field and preventing massive farms from dominating. These percentages can change over time and new algorithms can be easily dropped in. You can mine today using an old laptop and in 5 years you will still be able to. Incidentally, there is nothing standing in the way of adding mobile phone-based mining, which ETN showed there’s a huge demand for.
Based off the excellent Grin codebase, which means they continue to pull in ongoing core code enhancements and focus on ease of use and market penetration instead. (Smart!)
Litecoin’s Charlie Lee is out there daily talking about their move to Mimblewimble, which provides free publicity. What people don’t realize is that you can’t just bolt on Mimblewimble to a legacy blockchain, that’s like putting a Ferrari engine into a school bus - it’s still a school bus, not a race car! LTC is doing it as an optional soft fork via “extension blocks” which will not be supported by all wallets and exchanges. Also, anyone using “optional” privacy features is declaring themselves to be suspicious, which kind of defeats the point for people who care about privacy.
The community is friendly and welcoming to new people coming in, with lots of helpful (independently created) tutorials and guides. (F)
It’s already a global phenomenon, with the whitepaper in 20+ languages (G) and (not bot-infested) active local-language communities on not only Telegram but also Wechat, LINE, QQ and other messenger platforms.
It’s only on two random little exchanges currently, Citex and Vitex. Vitex is actually a pretty good DEX with no KYC and a great mobile wallet.
They are very creative - since centralized exchanges want huge money to list, they created a non-inflationary ERC20 tracker token that’s exchangeable 1:1 for coins so that Uniswap trading is possible (H)
Because it doesn’t have a huge marketing budget in a sea of VC-funded shitcoins, it is as-yet undiscovered, which is why it’s so cheap. There are only 4 Mimblewimble-based currencies on the market: MWC at $162m, BEAM at $26m, GRIN at $22m, and EPIC at $0.4m. This is not financial advice and as always, do your own research, but I’ve been buying this gem for months and will continue to. This one ticks all the boxes for me, the only real problem is that it’s hard to buy much without causing a huge green candle. Alt season is coming, and coins like this are how your neighbor Chad got his Lambo back in 2017. For 2021, McLaren is a better choice and be sure to pay cash so that it doesn’t get repossessed like Chad!
https://preview.redd.it/6w93e0afttx41.png?width=1400&format=png&auto=webp&s=c00989612ec2d52eb522405e6b6a98bf875e08bb Version 1.3.0 is a powerful update to TkeySpace that our team has been carefully preparing. since version 1.2.0, we have been laying the foundation for implementing new features that are already available in the current version. Who cares about the security and privacy of their assets is an update for you. TkeySpace — was designed to give You full control over your digital assets while maintaining an exceptional level of security, which is why there is no personal data in the wallet: phone number, the email address that could be compromised by hackers — no identity checks and other hassles, just securely save the backup phrase consisting of 12 words.
Briefly about the TkeySpace 1.3.0 update :
Code optimization and switching to AndroidX;
Selecting the privacy mode;
Selecting the recovery method for each currency;
Choosing the address format for Litecoin;
Enhanced validation of transactions and blocks in the network;
Starting with the current update, the TkeySpace wallet can communicate via the TOR network, includes new privacy algorithms, and supports 59 different currencies. https://i.redd.it/kn5waeskttx41.gif Tor is a powerful privacy feature for those who own large assets or live in places where the Internet is heavily censored.
Tor technology provides protection against traffic analysis mechanisms that compromise not only Internet privacy, but also the confidentiality of trade secrets, business contacts, and communications in General.
When you enable TOR settings, all outgoing traffic from the wallet will be encrypted and routed through an anonymous network of servers, periodically forming a chain through the Tor network, which uses multi-level encryption, effectively hiding any information about the sender: location, IP address, and other data. This means that if your provider blocks the connection, you can rest easy — after all, by running this function, you will get an encrypted connection to the network without restrictions. https://preview.redd.it/w9y3ax4mttx41.png?width=960&format=png&auto=webp&s=972e375fc26d479e8b8d2999f7659ec332e2af55 In TOR mode, the wallet may work noticeably slower and in some cases, there may be problems with the network, due to encryption, some blockchain browsers may temporarily not work. However, TOR encryption is very important when Internet providers completely block traffic and switching to this mode, you get complete freedom and no blocks for transactions.
Confidentiality of transactions (the Blockchain transaction)
The wallet can change the model of a standard transaction, mixing inputs and outputs, making it difficult to identify certain cryptocurrencies. In the current update, you can select one of several modes for the transaction privacy level: deterministic lexicographic sorting or shuffle mode.
Mode: Lexicographic indexing
Implemented deterministic lexicographic sorting using hashes of previous transactions and output indexes for sorting transaction input data, as well as values and scriptPubKeys for sorting transaction output data; We understand that information must remain confidential not only in the interests of consumers but also in higher orders, financial systems must be kept secret to prevent fraud. One way to address these privacy shortcomings is to randomize the order of inputs and outputs.
Lexicographic orderingis a comparison algorithm used to sort two sets based on their Cartesian order within their common superset. Lexicographic order is also often referred to as alphabetical order or dictionary order. The hashes of previous transactions (in reverse byte order) are sorted in ascending order, lexicographically.
In the case of two matching transaction hashes, the corresponding previous output indexes will be compared by their integer value in ascending order. If the previous output indexes match, the input data is considered equal.
Shuffle Mode: mixing (random indexing)
To learn more about how “shuffle mode” works, we will first analyze the mechanisms using the example of a classic transaction. Current balance Of your wallet: 100 TKEY, coins are stored at different addresses: x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
Addresses in the blockchain are identifiers that you use to send cryptocurrency to another person or to receive digital currency.
Let’s look at a similar example: you have 100 TKEY on your balance, and you need to send 19 TKEY. x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY. You send 19 TKEY, the system analyzes all your addresses and balances on them and selects the most suitable ones for the transaction. To send 19 TKEY, the miners will be given coins with x2. Addresses, for a total of 20 TKEY. Of these, 19 TKEY will be sent to the recipient, and 0.99999679 TKEY will be returned to Your new address as change minus the transaction fee. https://preview.redd.it/doxmqffqttx41.png?width=1400&format=png&auto=webp&s=5c99ec41363fe50cd651dc0acab05e175416006a In the blockchain explorer, you will see the transaction amount in the amount of 20 TKEY, where 0.99999679 TKEY is Your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee. The shuffle mode has a cumulative effect. with each new transaction, delivery Addresses will be created and the selection of debit addresses/s that are most suitable for the transaction will change. Thus, if you store 1,000,000 TKEY in your wallet and want to send 1 TKEY to the recipient, the transaction amount will not display most of your balance but will select 1 or more addresses for the transaction.
Selecting the recovery method for each digital currency (Blockchain restore)
Now you can choose the recovery method for each currency: API + Blockchain or blockchain.
Note: This is not a syncing process, but rather the choice of a recovery method for your wallet. Syncing takes place with the blockchain — regardless of the method you choose.
What are the differences between recovery methods?
API + Blockchain
In order not to load the entire history of the blockchain, i.e. block and transaction headers, the API helps you quickly get point information about previous transactions. For example, If your transactions are located in block 67325 and block 71775, the API will indicate to the node the necessary points for restoring Your balance, which will speed up the “recovery” process. As soon as the information is received, communication with the peers takes place and synchronization begins from the control point, then from this moment, all subsequent block loading is carried out through the blockchain. This method allows you to quickly restore Your existing wallet. ‘’+’’ Speed. ‘’-’’ The API server may fail.
This method loads all block headers (block headers + Merkle) starting from the BIP44 checkpoint and manually validates transactions. ‘’+’’ It always works and is decentralized. ‘’-’’ Loading the entire blockchain may take a long time.
Why do I need to switch the recovery method?
If when creating a wallet or restoring it, a notification (!) lights up in red near the selected cryptocurrency, then most likely the API has failed, so go to Settings — Security Center — Privacy — Blockchain Restore — switch to Blockchain. Syncing will be successful.
Enhanced validation of transactions and blocks in the network
Due to the increased complexity in the Tkeycoin network, we have implemented enhanced validation of the tkeycoin consensus algorithm, and this algorithm is also available for other cryptocurrencies.
What is the advantage of the enhanced validation algorithm for the user
First, the name itself speaks for itself — it increases the security of the network, and second, by implementing the function — we have accelerated the work of the TkeySpace blockchain node, the application consumes even fewer resources than before.
High complexity is converted to 3 bytes, which ensures fast code processing and the least resource consumption on your device.
The synchronization process has been upgraded. Node addresses are added to the local storage, and instant synchronization with nodes occurs when you log in again.
Checking for double-spending
TkeySpace eliminates “double-spending” in blockchains, which is very valuable in the Bitcoin and Litecoin networks.
For example, using another application, you may be sent a fake transaction, and the funds will eventually disappear from the network and your wallet because this feature is almost absent in most applications.
Using TkeySpace — you are 100% sure that your funds are safe and protected from fraudulent transactions in the form of “fake” transactions.
The bloom filter to check for nodes
All nodes are checked through the bloom filter. This allows you to exclude fraudulent nodes that try to connect to the network as real nodes of a particular blockchain. In practice, this verification is not available in applications, Tkeycoin — decided to follow a new trend and change the stereotypes, so new features such as node verification using the bloom filter and double-spending verification are a kind of innovation in applications that work with cryptocurrencies.
Updating the Binance and Ethereum libraries
Updated Binance and Ethereum libraries for interaction with the TOR network.
Function — to hide the balance
This function allows you to hide the entire balance from the main screen.
Advanced currency charts and charts without authentication
Detailed market statistics are available, including volumes, both for 1 day and several years. Select the period of interest: 1 day, 7 days, 1 month, 3 months, 6 months, 1 year, 2 years.
In version 1.3.0, you can access charts without authentication. You can monitor the cryptocurrency exchange rate without even logging in to the app. If you have a pin code for logging in, when you open the app, swipe to the left and you will see a list of currencies.
Transaction verification for Tkeycoin is now available directly in the app.
Independent Commission entry for Bitcoin
Taking into account the large volume of the Bitcoin network, we have implemented independent Commission entry — you can specify any Commission amount. For other currencies, smart Commission calculation is enabled based on data from the network. The network independently regulates the most profitable Commission for the sender.
New digital currencies
The TkeySpace wallet supports +59 cryptocurrencies and tokens.
Monnos and Nano: one more place to buy and sell Nano (thanks to the efforts of the brazilian community!) :)
Hi guys, how are you doing? First of all, I’d like to thanks Rafael Serrano, Guillermo Peccilli and all the brazilian community for supporting and inviting us to be part of the Nano network. We are really excited to be part of it. But straight to the point: I’m one of the partners of Monnos (you can check out our website here) and recently we’ve opened a survey to decide which crypto we should add to our portfolio, and, as you can imagine, Nano is going to be the one !!!A little bit of context: we have just launched our beta and we don’t have our own community yet, neither do we have a lot of users, so we started to ask people to contribute with the survey in many differents channels and groups. To be quite frank, we were not getting a lot of votes, and then, one day I have opened my CRM and I have seen more than 50 votes in 20 minutes, all for Nano. That’s when I have realized the brazilian Nano community have voted massively for it. Here’s the results: ![img](ftoxyz13xyr31 " ") And for this reason, our global users are going to have one more place to buy, sell and make strategies with Nano as an option. During the next week we will be announcing Nano in our platform ! You guys are all invite to download and try our APP (beta), it will be really important for us. We are getting a lot of feedback and making improvments really fast, always alongside to the crypto community. We already have 8 different cryptos: Bitcoin, Ethereum, Litecoin, Bitcoin Cash, Ripple, Binance Coin and Tether in our portfolio! (and now, Nano!!!!) * Download IOS, click here. * Download Android, click here. About Monnos: We are an All in one Crypto App, easy and safe to use . We have brought together Exchange, Multi-Wallet and our core functionality - Sync Strategy. With Monnos you will be able to synchronize your strategies with any users, or open your strategies to others: if he/she buys some Bitcoins, you buy too, if he/she sells Ethereum you sell as well. And, of course, if he makes profit, you make too. Here’s a video explaining the product:https://www.youtube.com/watch?v=IjoQyicmDOk Again, thanks for all the support and feedback, you can count on us in the Nano revolution!
Groestlcoin September 2019 Development Release/Update!
For a more interactive view of changes, click here In our current world; bordering on financial chaos, with tariff wars, Brexit and hyperinflation rife, you can count on Groestlcoin to consistently produce innovation that strikes to take the power away from the few and into the many, even after a full five and a half years of solid development. Here is what the team has already announced in the last 3 months since the last development update:
Groestl Nodes aims to map out and compare the status of the Groestlcoin mainnet and testnet networks. Even though these networks share the same protocol, there is currently no way to directly compare these coins in a single location. These statistics are essential to evaluate the relative health of both networks.
Shows Onion (Tor) nodes
Shows IPv6 nodes
Supports both main net and test net
Node Checker – Check the status of a remote node
Ability to download node data by CSV, JSON or TXT format
Ability to download unique address data by CSV, JSON or TXT format
This is a tool for creating unsigned raw Groestlcoin transactions and also to verify existing transactions by entering in the transaction hex and converting this to a human-readable format to verify that a transaction is correct before it is signed.
Create Raw Unsigned Groestlcoin transactions
Generates a QR code for the transaction
Compatible with most Groestlcoin wallets including but not restricted to Groestlcoin Core and Electrum-GRS
Estimates final signed transaction size
Taking a raw transaction format and shows its Transaction ID, Transaction Inputs and Outputs
AGCore is an Android app designed to make it easier to run a Groestlcoin Core node on always-on Android appliances such as set-top boxes, Android TVs and repurposed tablets/phones. If you are a non-technical user of Groestlcoin and want an Android app that makes it easy to run a Groestlcoin Core node by acting as a wrapper, then AG Core is the right choice for you.
Update to Groestlcoin Core 2.17.2
Switched to native builds via NDK for Groestlcoin Core resulting in a smaller footprint.
Added embedded tor
Added tor pairing support
TOR upgrade bug fixes
Improved blockchain Sync progress using getblockchaininfo verificationprogress
Improved package download progress bar
Added support for external storage access > Android M
Added support for Android Oreo, including new notification mechanism
Bump Fee (RBF) improvements – Implemented a new fee-bump strategy that can add new inputs, so now any transaction can be fee-bumped. The old strategy was to decrease the value of outputs (starting with change). We will now try the new strategy first, and only use the old as a fallback.
Coin Choser improvements
More likely to construct transactions without change (where possible)
Less likely to construct transactions with really small change
Only spend negative effective value coins when beneficial for privacy
Fix long-standing bug that broke wallets with >65k addresses
Windows binaries: Now build the PyInstaller bootloader ourselves, as this seems to reduce anti-virus false positives
Fix performance regression for large wallets
Fix high-DPI issues related to text fields
Trezor – Allow bypassing 'too old firmware' error
Trezor – Use only the Bridge to scan devices if it is available
Hardware wallets – On Win10-1903, some hardware devices with U2F functionality can only be detected with Administrator privileges. A workaround is to run as Admin, or for Trezor to install the Bridge.
The AppImage Linux x86_64 binary and the Windows setup.exe are now built reproducibly.
Fix watch-only wallets that could not bump fee in some scenarios
Faster transaction signing for segwit inputs or really large transactions.

Hey! I’m relatively new to Cryptos and the dark arts of how it ‘really’ works – I got into it because I heard that a friend of a friend had bought $13,000 worth of XRP at $0.30 and sold it all at pretty much the all time high. Naturally you could forgive me for thinking that this is easy! Since then I’ve tried trading and to be totally honest, it doesn’t play to my strengths. I’m at my best when I find an opportunity and hold (I make no apologies for spelling that correctly either!). I’ve only come across 3-4 coins that have caught my attention so far and I’ve been through nearly all of them in the top 300 and a lot of them outside of that (as well as multiple ICO’s). Now you know a little bit about my background and how I got into Cryptos – the purpose of this post is to help all the NEBL holders/owners out there understand that by leaving your NEBL in an online exchanges such as Binance you are letting them earn interest on your investment! Nebilo is a Proof of Stake (PoS) coin and PoS is a category of consensus algorithms for public blockchains, which Neblio’s algorithm is a part of. It serves a similar function to the proof of work which underpins the security behind Bitcoin, but has significant advantages in terms of security and energy efficiency. There are multiple links that I used to get me set up, as well as some really useful help from Telegram user ‘rejoin**’ The only problem was that to someone who has completely no idea about how to use anything other than Microsoft Excel, Word or Powerpoint – answers like ‘it’s simple’ weren’t really what I was looking for. Cutting to the chase – here is a full guide to help people with ‘staking’ https://nebl.io/2017/07/01/staking-explained/ for the Raspberry Pi 3 – it should however help anyone looking to stake as the basic principles are the same across the board. Step 1 - Buy the Pi Assuming that you’re here because you’ve already bought NEBL – the first thing that you need to do is decide what device you want to stake on. Personally I went for the Raspberry Pi 3 (RP3) – it’s low energy consumption and it was as simple as that for me. I bought mine on Amazon for around £45 - https://www.amazon.co.uk/Raspberry-Pi-Official-Desktop-Startedp/B01CI58722/ref=sr_1_5?s=computers&ie=UTF8&qid=1517059342&sr=1-5&keywords=raspberry%2Bpi%2B3&th=1 Step 2 - Setting up the Pi The lovely postman turns up and hands you your package – opening it is quite an experience in itself, there is virtually nothing there, apart from a circuit board, power cable and a few bits of plastic. Prepare to be amazed! To get set up – the best work through I found is this video. https://www.youtube.com/watch?v=gbJB3387xUw Apologies in advance, but that isn’t Donald Trump. Looks pretty close though. Step 3 - Download the wallet There are lots of wallets to choose from - https://nebl.io/wallets/ - but for the sake of this how to guide – make sure you go on your RP3 and download the RP3 wallet. You can either copy the script from the webpage – or this post. You will need to click on the ‘Terminal’ on the RP3 – paste this exactly into the terminal and it will start to install the wallet. The terminal can be found pinned to the taskbar on the RP3 - it looks a bit like the 'run' feature on Windows. 'curl https://raw.githubusercontent.com/NeblioTeam/NEBL-Pi/masteNEBL-Pi-Installer.sh | bash -s -- -q' I don’t know about you – but I was already pretty amazed at this point (doesn’t take a lot… I know). Step 4 - Syncing Once you’ve done the step 3, you should be presented with a neblio wallet on your RP3 desktop. We’ll leave that bit there for now – it will need start to sync and you’ll see a certain number of blocks processing etc, so now we need to concentrate on getting yourself set up with a firewall and making sure your RP3 doesn’t power down (if it does, then your node will not count at active and staking will not be live). Step 5 – Encrypt your wallet This is a very important part of the process – to stake, your wallet must be unlocked, but encrypted – make sure you take the time here to set a complex password that only you know. To encrypt your wallet – click on ‘settings’ and then ‘encrypt wallet’. Step 6 – Downloading a firewall Now you’re welcome to google this (I did when it was explained to me), so once you have – go to your terminal again and type in the following one after another. sudo apt-get install ufw –y (copy, paste and then press enter) sudo ufw enable (let it run, copy, paste and then press enter) sudo ufw allow 6325 (let it run, copy, paste and then press enter) Step 7 – Setting your RP3 to stay awake (Optional - I did this purely for peace of mind) There might well be a better way of doing this and if there is, please let me know and I’ll update this post… but this was the best video I found for this was here - https://www.youtube.com/watch?v=hWKSTsWwOTk I went into the feature that you install and set all the minutes to the highest possible values (which I believe are 720 minutes). Step 8 – Send your NEBL’s Now that you have your wallet set up with firewall and the RP3 won’t sleep – It’s time to get move your NEBL’s from Binance or whatever other exchange you’re using. Click on ‘receive tokens’ and you’ll be presented with your wallet address. I always send 1 token first to test the route works – yeah you get charged 0.01 NEBL, but for me I prefer the safety route first. The only thing to note is that it is best to stake in as higher group as possible. If for example you have 1000 NEBL and you transferred them across in 4 batches of 250 – you would have 4 staking groups of 250 each. If you’re OK with sending them to yourself in one go, then go for it and we’re nearly there! Step 9 – Unlock your wallet In order to stake, you must have your wallet open – this allows you to become part of the blockchain and act as a node in the wider Neblio network. Through being open you process the transactions through the network and earn fees. Step 10 – Wait and earn! Now that you’ve got all your NEBL’s in your wallet and it is unlocked and encrypted (please make sure you’ve done this!!) it will take 24 hours at least for your coins to mature, you will see a stack of coins in the bottom right hand corner, when these are white it means they are not currently staking. As soon as these have changed to black, it will tell you your weight and how many days until you get your reward for supporting the Neblio Blockchain! If anyone found this step by step guide of any use – Any donations gratefully received! Oh... and please backup your wallet! There are guides for this when you download the wallet.

[Dev-Happy] Blondfrogs05/10/2019 Channel should be open now Chill05/10/2019 you all rock! just getting that out of the way :wink: Tron05/10/2019 Cheers everyone. theking05/10/2019 Hi fabulous dev team! Hans_Schmidt05/10/2019 Howdy! Tron05/10/2019 No specific agenda today. Questions? Has everyone seen Zelcore wallet, and Spend app? theDopeMedic05/10/2019 Any major development status updates that haven't been listed in #news? Synicide05/10/2019 How was the meetup yesterday? I heard it would be recorded, it is uploaded anywhere yet? Tron05/10/2019 And Trezor support on Mango Farm assets? @Synicide Yes it was recorded. The Bitcoin meetup organizer has the video. I talked about Ravencoin, but mostly about the stuff that was being built on/with/for Ravencoin. There was about 70% overlap with folks who were at the Ravencoin meetup in March. Synicide05/10/2019 awesome, looking forward to watching it when it's available Tron05/10/2019 I'll hit up James and see if he's posting the video. S1LVA | GetRavencoin.org05/10/2019 @theDopeMedic I'd follow github if youre interested in development status Synicide05/10/2019 zelcore looks super slick. Been meaning to research its security more with the username/pw being stored on device Chill05/10/2019 How is the progress on the restricted assets and testnet coming along? A secondary question would be about the approximate fork timeframe. S1LVA | GetRavencoin.org05/10/2019 Has anyone heard from the community dev (BW) working on Dividends? Rikki RATTOE Sr. SEC Impresantor05/10/2019 Any word on BW and his progress w dividends? @S1LVA | GetRavencoin.org LOL Tron05/10/2019 @S1LVA | GetRavencoin.org Great question. I haven't heard. Synicide05/10/2019 last meeting BlondFrogs said he would try to connect with BW as he was sick with the flu at the time. Maybe he has an update S1LVA | GetRavencoin.org05/10/2019 I've tried to get in contact, but with no success. Rikki RATTOE Sr. SEC Impresantor05/10/2019 Got a funny feeling... Jeroz05/10/2019 Last time we left off with someone mentioning a foundation and Tron saying let’s discuss that next time iirc kryptoshi05/10/2019 Has anyone taken a look at the merits for this proposal? Thoughts? https://medium.com/systems-nexus/modified-x16r-algorithm-proposal-for-constant-hash-rate-in-short-time-164711dd9044 Medium Modified X16R algorithm proposal for constant hash rate in short time Interpretation Lens V. a0.01 Tron05/10/2019 I did see it. Does anyone think this is a problem? Synicide05/10/2019 It looks interesting... but I'm not sure what it is trying to solve. Looking at netstats, our 1 hour average block time is perfectly 1 minute S1LVA | GetRavencoin.org05/10/2019 Last I heard from him he expressed how important finishing the code was. I wouldnt jump to conclusions on his absence within the community. Synicide05/10/2019 x16r by nature will fluctuate, but DGW seems to be doing a good job keeping consistent block times Tron05/10/2019 Because of relatively broad distribution across the algorithms, the block times are fairly consistent. It is possible, but very, very unlikely to get a sequence that takes up to 4x longer, but that's super rare, and only 4 minutes. We did some timing analysis of the algorithms early on. A few are 1/2 as long as SHA-256 and some are up to 4x longer. But when you randomly select 16 it usually comes out about even. Synicide05/10/2019 1hr avg: 1.02min - 24hr avg: 1min I think we should focus on building, and not trying to fix what isnt necessarily broken Tron05/10/2019 Agreed. Rikki RATTOE Sr. SEC Impresantor05/10/2019 Agreed Tron05/10/2019 Is everyone ok with the frequency (every other week) of this discussion? Jeroz05/10/2019 (Added thumbs down to measure) Tron05/10/2019 @Jeroz Did you do thumbs-up and thumbs down? S1LVA | GetRavencoin.org05/10/2019 Seems appropriate. Its not like the devs dont poke around here and chat anyways. Tron05/10/2019 Anything critical that we should be aware of? Jeroz05/10/2019 When I need a dev, I poke a dev. When that dev is unavailable. I poke another one :smiley: Hans_Schmidt05/10/2019 BlondFrogs was testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends. Jeroz05/10/2019 I hope I didn’t offend any devs With poking around Rikki RATTOE Sr. SEC Impresantor05/10/2019 Was thinking voting would be an excellent use case for restricted assets. Local communities, nations, etc... could kyc their residents radiodub05/10/2019 Is x16r will remain fpga mineable Tron05/10/2019 @Jeroz We're hard to offend. Chill05/10/2019 Is the general dev feeling that the next fork should and will include everything needed for the next 6-9 months (barring something completely unforeseen)? Jeroz05/10/2019 I know :smile: Tron05/10/2019 @radiodub Nearly impossible to stop FPGAs and still keep GPUs Jeroz05/10/2019 About that: voting is another hard fork right? Not too soon? Tron05/10/2019 FPGAs can be reprogrammed as fast. It is silicon (true ASIC) that we can obsolete with a tiny change. @Jeroz Messaging, voting, Tags, Restricted Assets would require a hard fork (upgrade). We could do them each individually, but folks get weary of upgrades, so current plan is to roll them together into one. MrFanelli™05/10/2019 Good idea Jeroz05/10/2019 Oh voting too? MrFanelli™05/10/2019 People will like that Jeroz05/10/2019 I thought that was coming later Tron05/10/2019 Voting is the one that isn't being worked on now. Tags and Restricted assets have taken precedence. Jeroz05/10/2019 I know. But you plan on waiting to fork until voting is also done? That would have my preference tbh But I can see an issue with too many things at the same time Tron05/10/2019 If someone wants to step in, we've had one of our devs sidelined and he was working on BlockBook support so more light wallets can connect to Ravencoin. Mostly test cases needed at this point. S1LVA | GetRavencoin.org05/10/2019 Thats a pretty large upgrade.. Bigger surface for unknowns Rikki RATTOE Sr. SEC Impresantor05/10/2019 At what point would RVN community consider moving to ASICs because having a Bitcoin level of security would eventually be needed? MrFanelli™05/10/2019 Never rikki Tron05/10/2019 @S1LVA | GetRavencoin.org 100% Lots of testing on testnet and bounties. [Dev-Happy] Blondfrogs05/10/2019 I am here :smiley: Tron05/10/2019 @Rikki RATTOE Sr. SEC Impresantor There's nothing inherently wrong with ASICs but it tends to centralize to data centers and less opportunity for anyone to just run their gaming rig overnight and collect RVN. Welcome Blondfrogs MrFanelli™05/10/2019 Asics are too expensive. If we want normal people to mine, then we cant be an asic network Rikki RATTOE Sr. SEC Impresantor05/10/2019 @Tron True but what happens when the chain needs a Bitcoin level of protection? Tron05/10/2019 More GPUs, more FPGAs MrFanelli™05/10/2019 Nvidia loves ravencoin :stuck_out_tongue: Chill05/10/2019 ok, so we are pro FPGAs 𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/10/2019 Build it and they will come Tron05/10/2019 It's all relative. It is cost to attack. If an ASIC isn't available for rent, then only option is rental of non-allocated GPUs Rikki RATTOE Sr. SEC Impresantor05/10/2019 @Chill Eventually everyone will need FPGAs to be profitable on RVN, at that point I don't see why we just don't make the switch to ASICs Tron05/10/2019 Also, as much as we don't focus on price, the price does matter because it determines the amount of electricity and hardware will be deployed to get the block reward. Price increase means more security, more mining means more security means higher price. It's a circle. Chill05/10/2019 someone tell that to the twitter handler HailKira05/10/2019 you guys adding seedphrase to desktop wallet? [Dev-Happy] Blondfrogs05/10/2019 @HailKira We will, just is not a high priority right now. MrFanelli™05/10/2019 Twitter handle wants rvn ded Rikki RATTOE Sr. SEC Impresantor05/10/2019 I just don't see much difference between ASIC and FPGA and I'd rather have the added nethash an ASIC will provide once GPUs are virtually kicked off the network kryptoshi05/10/2019 I'm at 11 GB future proof Tron05/10/2019 That also limits miners to big money, not gaming rigs. Synicide05/10/2019 @Rikki RATTOE Sr. SEC Impresantor you have to keep in mind the 'added nethash' is all relative Rikki RATTOE Sr. SEC Impresantor05/10/2019 FPGAs will limit miners to big $$$ too IMO Tron05/10/2019 @kryptoshi New algo x16r-12G requires 12GB :frowning: Seal <:cricat:> Clubber05/10/2019 But sperating smaller gb cards would lead to less adoption if we ever become a mainstream coin. Adpotion of mining that is Chill05/10/2019 but we are a mainstream coin Seal <:cricat:> Clubber05/10/2019 Mains stream as in what eth did Tron05/10/2019 @Rikki RATTOE Sr. SEC Impresantor I agree. Not a perfect solution. Steelers05/10/2019 Is this a Dev meeting or Algo meeting :smiley: Seal <:cricat:> Clubber05/10/2019 But if we ever go mem lane. We should aim for 6 or 8gb. Tron05/10/2019 Open to other questions. Rikki RATTOE Sr. SEC Impresantor05/10/2019 @Tron Probably not the time and the place to have this discussion as we stand currently but IMO we're gonna have this conversation for real eventually Seal <:cricat:> Clubber05/10/2019 Most cards have 6gb now. kryptoshi05/10/2019 Why 12 gb ? Such a massive jump Seal <:cricat:> Clubber05/10/2019 ^ Would also like to know Tron05/10/2019 @kryptoshi I was joking. You said you had 11GB card. Seal <:cricat:> Clubber05/10/2019 Haha You got em good I cant imaghine the face he had when he was 1gb short Lel Rikki RATTOE Sr. SEC Impresantor05/10/2019 That's what she said kryptoshi05/10/2019 Hahaha MrFanelli™05/10/2019 need a 2080ti Seal <:cricat:> Clubber05/10/2019 How much does the VII have? 16? [Dev-Happy] Blondfrogs05/10/2019 Any other questions you have for us? Hans_Schmidt05/10/2019 @[Dev-Happy] Blondfrogs You were testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends. Chill05/10/2019 a dev might want to contact Crypto Chico for some 'splaining [Dev-Happy] Blondfrogs05/10/2019 I still haven't contacted the developer that was working on dividends. Was pretty busy with some other stuff. I will contact him this next week, and see where we are at for that. Rikki RATTOE Sr. SEC Impresantor05/10/2019 Chico doesn't do interviews, shame. Tron would be a much needed interview for his community [Dev-Happy] Blondfrogs05/10/2019 As far as releasing dividends, I can be released at anytime the code is finished and doesn't require any voting or hardfork to occur kryptoshi05/10/2019 Android asset aware wallet? Seal <:cricat:> Clubber05/10/2019 Is in beta right Tron05/10/2019 Testing went well today on Android. Nearing release. [Dev-Happy] Blondfrogs05/10/2019 as it is a mechanism that is wallet specific liqdmetal05/10/2019 no protocol level dividends you guys are saying? [Dev-Happy] Blondfrogs05/10/2019 correct Tron05/10/2019 DM me if you want to test Android with Asset support. I'll send you the .APK. Rikki RATTOE Sr. SEC Impresantor05/10/2019 RVN gonna be on tZero wallet? :yum: liqdmetal05/10/2019 why not? what is the logic on non-protocol dividends assets + protocol dividends is nirvana [Dev-Happy] Blondfrogs05/10/2019 dividends is pretty much sending payments to addresses. Right now, you would have to do this manually. The dividends code, will allow this to be done quicker and easier. No consensus changes are required. Tron05/10/2019 New Android wallet is BIP44 and original Android wallet is BIP32/BIP39 so the words will not find the funds. You'll need to send them to another wallet, and then send them to new BIP44 derived address. liqdmetal05/10/2019 we already have payments to addresses so dividends is not a feature so much as simple wallet script Hans_Schmidt05/10/2019 @[Dev-Happy] Blondfrogs The dividend code changes look risky'er to me than messaging. Would you consider "tags" branch test-ready? [Dev-Happy] Blondfrogs05/10/2019 Not yet @Hans_Schmidt Dividends is easier then you would think if coded correctly. I still haven't seen the code from the community developer. Excited to view it though. Hans_Schmidt05/10/2019 @[Dev-Happy] Blondfrogs Sorry- I meant restricted, not dividend kryptoshi05/10/2019 @Tron on the Android wallet, anyone successfully added their own node and got it to sync faster? Always have issues. I have a supped up node and cannot get it to work with the Android wallet... [Dev-Happy] Blondfrogs05/10/2019 @Hans_Schmidt Oh, that makes more sense. Yes, they are very risky! That is why we are going to create a new bug bounty program for restricted assets testing. Rikki RATTOE Sr. SEC Impresantor05/10/2019 Once the network does get flooded w FPGAs, should we even consider changing the algo a couple times a year? That would only give bitstream developers added time to hoard their creations for themselves Kind of like they're already doing with their x16r bitstreams :yum: kryptoshi05/10/2019 Flooded... lol... like that hardware has mass production scale like gpus...come on dude MrFanelli™05/10/2019 Bip44 wallet? :smiley: Rikki RATTOE Sr. SEC Impresantor05/10/2019 @kryptoshi Eventually yes, where there's $$$ to be made, people make things happen MrFanelli™05/10/2019 So can we trade from that in the new Binance Dex when RVN get listed? kryptoshi05/10/2019 @Rikki RATTOE Sr. SEC Impresantor Yes Soon TM lol. :soontm: Tron05/10/2019 @kryptoshi There are some things we can do to speed it up. For a new wallet, it shouldn't need to sync. For recovered wallet, it needs to sync from beginning of BIP44 wallet support on iOS so words can be moved between the two. Other options include grabbing the first derived address and looking it up on an explorer to see when it was first used and sync from there. Another option is to add an optional number with the 12 words so it knows when to start syncing. There isn't a good reason on an SPV wallet to sync before the seed was created. kryptoshi05/10/2019 Cool. Glad you are looking at speedup options.. :right_facing_fist: :left_facing_fist: [Dev-Happy] Blondfrogs05/10/2019 @MrFanelli™ If the binance dex support RVN deposits. I am sure you would be able to send from it MrFanelli™05/10/2019 Has binance reached out for any info or anything? I seen that we ranked in some voting competition they had on twitter for an ama Rikki RATTOE Sr. SEC Impresantor05/10/2019 I believe we'll need to create a fund of approximately $300,000 in order to get a BNB-RVN asset created and listed on the Binance FDEX [Dev-Happy] Blondfrogs05/10/2019 In order to work with binance we need Ravencoin integrated into Blockbook. Tron05/10/2019 @MrFanelli™ I've reached back out to Binance on the AMA. MrFanelli™05/10/2019 Awesome :smile: kryptoshi05/10/2019 @Tron you are a natural on the interviews... cool as a cucumber. :sunglasses: Tron05/10/2019 Thanks @kryptoshi [Dev-Happy] Blondfrogs05/10/2019 Cool. We are done for today. Please don't ask us any more questions :smiley: Tron05/10/2019 Thanks everyone!!!! [Dev-Happy] Blondfrogs05/10/2019 Cya everyone!! S1LVA | GetRavencoin.org05/10/2019 Cya happy feet, Thanks Thanks Tron Seal <:cricat:> Clubber05/10/2019 :bepbep:
Hello! My name is Inna Halahuz, I am a sales manager at Platinum, the largest listing service provider for the STO and ICO projects. We know all about the best and most useful STO and ICO marketing services. By the way, we developed the best blockchain platform: [Platinum.fund] (https://platinum.fund/sto/) We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms. What a Blockchain Wallet is? What is its purpose? Find the answer after reading this article. Public/Private Key The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver. Accessing wallets Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals. Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets. Types of Wallets & Storage Methods The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners. Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens. Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples. Hardware wallets — LedgeTrezoAlternatives Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers. Paper Wallets Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper! Real World Historical Examples of Different Wallet Types Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops. Neon Wallet The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible. Real World Example — Poor Practices MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets. In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes. Case Study: Good Practice Binance, the Attempted Hack During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt. Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange. Hardware Wallets Advantages and Limitations We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations. Paper Wallets Advantages and Limitations Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever. Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose. You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait. How to Monitor Funds There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor. That’s not all!

[uncensored-r/CryptoCurrency] XRB is hyped up vapourware and will never work as advertised. Don't buy into the pump scheme.. if...
The following post by ethswagholder is being replicated because some comments within the post(but not the post itself) have been openly removed. The original post can be found(in censored form) at this link: np.reddit.com/ CryptoCurrency/comments/7qbixo The original post's content was as follows:
XRB rai blocks has massive issues which will never get resolved. The developers have been making promises to resolve these node/exchange issues for almost a year now. The latest promise is that "it will be resolved early next week" but anyone who isn't blind to the obvious facts can wager that it will definitely not get resolved. This is the XRB cryptopia de-listing message, which also talks about these sync issues. This was almost a year back. The XRB shills want to pretend the cryptopia delisting was only due to death threats from third world captcha farmers, but the issues were simply because the coin has huge issues even back then. The Cryptopia node simply kept crashing and for days the coins were not accessible. The wallet on cryptopia exchange site said frozen for several days, and suddenly one day they would enable deposits and withdrawals, but in a couple of hours it would go down again. This kept happening time and again... people sent their coins to cryptopia, but they never arrived in the wallets. Withdrawals, same story, disabled. They tried reaching Cryptopia support who in their capacity also tried to fix this issue and get the wallets running, but again it would go down in next to no time. Rise and repeat. People were waiting for the withdrawals and deposits for weeks on end, and after a while even they got fed up with the lack of support. Then naturally, the blame game started and the accusations fell on Cryptopia. And ofcourse, some people reacted badly with death threats etc.. Cryptopia talks about of all these problems including death threats and network issues in their delisting message. It is not down only to "Death threats", but a chain of events culminating in the threats... Now fast forward 8-9 months since then, and what do you have? All exchanges are still not working. Bit Grail owner publicly stated he is being insulted, called a scammer, and he was given the twitter abuse by the community too, when all he did was say the truth that there are HUGE issues which are outside both his and developers control... Merca tox is down for god knows how many days, there is constant reports that Mercatox has scammed, pursue legal action, etc. At this point, from abuse and legal threats, to death threats... it is not a giant leap.. especially when people believe they are losing money. There is a major issue with the coin. It cannot be resolved in a suitable manner that will enable smooth functioning of exchanges. No exchange will be able to run seamlessly like they are supposed to, because of severe limitations of the network and nodes. When there is small 100k volume, this is not a problem, when the volume scales, this will always result in huge back log of support tickets, deposits not working, withdrawals not working, blame game, finally legal threats... the cycle goes on.. There was a full cycle of these threats with Cryptopia and now very close to the legal/death threat phase of Merca tox and Bit Grail. If you read the XRB subs/twitter, many are abusing the owners of Bit Grail, someone wanted to visit Bit Grail office. They want to "sue" Merca Tox The "great" community.. even that can turn bad in no time, when money is involved.. You can never predict what people will do when they are waiting for several weeks for their coins. Its almost preposterous to think it would be any other way, but heck, coin went on KuCoin and same outcome. Surprise surprise. Notice how it is always blamed on the "shitty" exchanges alone by XRB shills. The same issues with Rai Exchange as well. Today Rai Exchange actually posted that "they have troubles integrating Litecoin"Source.. Hahaha ... If they can't integrate Litecoin, how the bloody hell will they integrate XRB the exchange killer? It is obvious the whole episode this is nothing but an elaborate scheme played to pump the coin from #200 in CMC to #15... Anyone thinking Binance the biggest exchange is gonna touch this toxic coin is out of his mind. It won the vote, but actually listing it is a different matter altogether. Adding such a crappy coin will harm Binance's reputation; especially after seeing KuCoin suffer. Even if they actually list it, and the same issues happens once again, it will be obvious to everyone that there is huge flaws in the system. The whitepaper and technology is great, but if implementation is impossible then there is no hope. The value will come tumbling down. These issues were brought to the developers as early as March 2017. They cannot be fixed unless there are serious changes made to the concept of raiblocks. If there is no solution, all investors may be sitting on highly combustible vapour. You need to understand the history of this issue and for how long it has been happening, and can't simply brush it aside crucial issues unsolved for almost a year now as "third world death threats"... or exchange issues which "will be resolved". If the developers were smart they will be on an island sipping their cocktails after the massive pump. No one has ever seen the lead developer, apart from his Linked In profile. He has never done any interview or even a video, outside of reddit AMAs. There is no reason to believe they have not pulled a Joost with their money (worth approx. $100m) after a successful hype driven pump campaign, instead of working on issues that cannot be resolved. Right now the coin has little bit of value left, if you are smart with your investments, you will know what to do.. If you can actually deposit that into an exchange, that is... If anyone tries informing their echo chamber subs about these issues, the posts get deleted faster than this coin's transaction times. Abuses get hurled along with the customary "Thxn, just bought more" Lol.. Those echo chambers actually believe this coin will "replace Bitcoin". They fail to realise that hundreds of coins have come and gone trying to replace bitcoin (each with a different tricky idea) while Bitcoin has not moved an inch from the top spot. This one and its toxic community of shills will learn a hard lesson not to buy every random reddit pumped coin especially when everyone else has done accumulating it.
